Help with persist command

Are you asking to persist on both the IP address and the string together?

If so, simply use UIE persistence and concatenate the two together like so:

 
 rule my_uie { 
    when HTTP_REQUEST { 
       persist uie [concat [IP::remote_addr] [HTTP::header "MyHeader"]] 
    } 
 } 
 

I should probably have explained a bit more in depth what I'm trying to do.

 

 

I have two pools of serves. Server A in one pool does a POST to the other pool. The reply (from server B), will contain a unique identifier. Later on server B will post a message back saying that it is done with processing the message. I want that (based on the same unique identifier), to persist back to server A. It's a bit backwards...

Ok, this is an excellent example for using the session cmd.

 

 

First, you will want to extract the unique Identifier and on the first request do a "session add uie $unique_id [IP::client_addr]" to save the original host that was used.

 

 

Then when the successive posts comes in, you'll want to extract the unique identifier, look it up in the session table with "session lookup uie $unique_id" and if it contains a value, use that host with either the "pool member " or the "node " command.
